In the lead up to Black Friday and Christmas this scam has been doing the rounds recently. It’s not new but it’s on the increase. If you receive a package that is unexpected, it may be a brushing scam that online sellers use to falsely inflate review ratings and may mean your personal data has been compromised.It involves people receiving an unexpected package from, for example, Amazon. You receive an unexpected package on your doorstep. It’s addressed to you so you open it and realise this was not something that you ordered. It could be an honest mistake somewhere up the line, but equally it could be what’s become known as a “Brushing Scam”.Most e-commerce businesses such as Amazon or eBay sellers, rely on positive reviews and bold sales numbers to build their reputation. Brushing scams are used to game their apparent ratings and sales numbers. The scam itself is not necessarily overly dangerous to you if you receive an unexpected package, but it could also be an early warning that your identity has been compromised and you could become the subject of identity theft.The user of a Brushing Scam gets your name and address. Then they set up a fake account in your name and then create the order. You receive the order, but then the scammer posts a fake review, 5-stars of course, in your name. The review is marked as a “verified buyer” because it has your name on it, linked to the fake account.There’s no return address. And they use the “sale” to boost their numbers, which in turn boosts their ranking on the e-commerce site. Unscrupulous sellers repeat this hundreds or thousands of times to drive up review standings and drive real purchases.There has been a lot of this kind of scam in the US and Canada, but it’s on the rise in the UK. The first brushing scams reported were, slightly bizarrely, when ‘mystery seeds’ started arriving from China in 2015. Whilst it’s not overly dangerous to you directly, it reduces the reliability of product reviews and perhaps more crucially, it reveals how your personal data can be so easily stolen by hackers and used by scammers.READ MORE: Facebook Marketplace scams – four ways to avoid being a victim In the lead up to Black Friday and Christmas a brushing scam has been doing the rounds recently (Image: GETTY)Free eBay package?
